note 112730 added to language.operators.arithmetic

The % operator doesn't behave as many people with a maths background would expect, when dealing with negative numbers. For example, -1 mod 8 = 7, but in PHP, -1 % 8 = -1. The following function has the expected behaviour: function mod($a, $n) { return ($a % $n) + ($a < 0 ? $n : 0); } mod(-1, 8) returns 7 as expected. ---- Server IP: 94.76.225.145 Probable Submitter: 62.172.216.8 ---- Manual Page -- http://php.net/manual/en/language.operators.arithmetic.php Edit -- https://master.php.net/note/edit/112730 Del: integrated -- https://master.php.net/note/delete/112730/integrated Del: useless -- https://master.php.net/note/delete/112730/useless Del: bad code -- https://master.php.net/note/delete/112730/bad+code Del: spam -- https://master.php.net/note/delete/112730/spam Del: non-english -- https://master.php.net/note/delete/112730/non-english Del: in docs -- https://master.php.net/note/delete/112730/in+docs Del: other reasons-- https://master.php.net/note/delete/112730 Reject -- https://master.php.net/note/reject/112730 Search -- https://master.php.net/manage/user-notes.php
